• Input Range: ±15 pF
is a very low-power, low-cost, high-resolution
• Measurement Resolution: 0.5 fF
contactless sensing technique that can be applied to
• Maximum Offset Capacitance: 100 pF
a variety of applications ranging from proximity
detection and gesture sensing to material analysis
• Programmable Output Rates: 100/200/400 S/s
and remote liquid level sensing. The sensor in a
• Maximum Shield Load: 400 pF
capacitive sensing system is any metal or conductor,
• Supply Voltage: 3.3 V
allowing for low cost and highly flexible system
design.
• Temp Range: –40 to 85°C
• Current Consumption:
The FDC1004 is a high-resolution, 4-channel
capacitance-to-digital converter for implementing
– Active: 750 µA
capacitive sensing solutions. Each channel has a full
